Error description

  • AIX backup-archive client builds are not properly setting the
maxdata flag to allow more than 256MB of memory to be used.
Without this, the client is likely to hit apparently random core
dumps as memory allocations fail.

Local fix

  • There is a command that can be used to repair the dsmc binary
after compile as a workaround.

The following is an example of a command that can repair the
dsmc program:

/usr/ccs/bin/ldedit  -b maxdata=0x80000000/dsa dsmc
